<br />The rough grading of the backfill area will produce as many flat <br />areas as possible but will leave the surface in a somewhat rough <br />condition on the contour. This resulting rough condition will <br />increase rainfall infiltration needed to promote plant establishment <br />and growth. In addition, it will also aid to reduce water and wind <br />erosion and provide a topographic surface which is similar to pre- <br />mining conditions. Smooth compacted surfaces along long slopes will <br />be avoided by grading along the contour and leaving the surface in <br />this rough condition. GEC Minerals, Inc. plans to restore the <br />surface to the approximate original contour as shown on the Post- <br />Mining Topography Map No. 23 and will match the overall approximate <br />pre-mining grades. Appropriate cross sections which show the pre- <br />mining and post-mining surfaces are also included on Cross Section <br />Map No. 25 and 26 of the mine plan area. Existing drainages will <br />be restored to the original location and elevation as shown on the <br />• Post-Mining Topography P1ap 23 and Cross Section Map No. 25 and 26. <br />In addition, the major existing drainage channel passing Northeast <br />through the mine area between the two planned mine areas which has <br />been disturbed during previous early mining will be reestablished <br />to its approximate original contour. <br />GEC Minerals, Inc. currently plans to continue to monitor all <br />regraded areas. In the event that gullies and rills in excess of <br />nine (g) inches in depth occur, the areas will be regraded and <br />revegetated in an effort to restore the area to its original state <br />and minimize erosion of the area. <br />Topsoil and Subsoil Redistribution Plan. Prior to the application <br />and redistribution of topsoil and subsoil materials, spoil will be <br />graded along the contour to minimize erosion, ensure its stability <br />and minimize slippage. As previously mentioned, this rough grading <br />will leave the overburden in a rough condition to ensure that <br />subsoil and topsoil materials bond to this surface to prevent <br />. slippage. <br />2.05-25 <br />
